Asinine. This confuses several issues. Remember, we're discussing this in the context of vaunted "Originalism." Originalists are not supposed to pick n' choose what they want to believe; they're supposed to interpret the Constitution in accordance with the intentions of the framers (or what legislators ratifying the Constitution believed at the time). You've parroted the familiar talking points in the case of Roe: The word "privacy" never comes up in the Constitution, let alone "abortion." Judicial restraint demands leaving the matter to legislators, especially at the state and local levels (compare with anti-sodomy laws).
Yet, yet, yet, this same logic does not apply to weapons with regard to public safety because... the Second Amendment?? Never mind how the Marshall(!) Court ruled in Barron v. Baltimore. Are you referring to some other penumbra or emanation in the Constitution? As far as I know, there is no mechanism in the Originalist view, unless you want to say we did not "really" have the right to own guns until the 14th Amendment. A mechanism given to Congress was the "Necessary and Proper" clause. Do "Originalists" welcome a broad reading of the Elasticity clause? What about the Commerce clause? "Federalism for thee but not for me."
If you don't like state and local gun laws, vote in a new slate of legislators. If you want to say the Constitution protects a right to own weapons unconnected from militia service, then quote from the document. Or cite framers or legislators saying something to that effect. Or do anything because right now you're just failing and flailing. What you could do is bite the bullet.
